Genus Archisotoma Linnanieni 1912.

Archisotoma brucei Carpenter 1906.

This is a very interesting littoral species which was described from the South Orkney Islands. From the closely allied form from the Northern Hemisphere it differs mainly in possessing only 6 ocelli on each side. The discovery by Mr Pritchard of this subantarctic insect so far north as Little Oneroa, Waiheke Island, Auckland (19–20/1/34), is therefore of great interest from the point of view of geographical distribution. The specimens were found amongst shore debris.
